where is the fuse

I have a Hymer Exsis sitting on a Fiat Ducato 2004. It is the 2.3 diesel jobby. I have 2 cigar lighters at the front and they have both blown fuses. I found the one for the actual cigar lighter and replaced it. That now works fine. But the other is called "current connector". To all intents and purposes it it just another cigarette lighter.

The diagram in the manual identifies it on the dashboard but it does not appear on the fuse list. I know it is 15 amp and I have looked at all my 15 amp fuses; they are all ok now that I have replaced the first blown one.

It is just possible that a previous owner replaced a 15 amp with something else and for that reason I can't spot it. If anybody knows where it is I would be so grateful.
Thanks Bernard

If you think this is rubbish - wait till you read "When can it do Errands?"

You may also like to check the fuses that are built onto the positive connection on the battery, but check the alternatives first as it a bugger of a job getting at the fuses, you have to remove the battery and the fuses are bolt on types.
